So you are planning a trip to Australia and hope to find a few caches while you are here but you're not sure how to find Caches nearby to where you will be staying?

Australian Postcodes (You might know them as ZIP codes) are 4 digits.
www.austpost.com.au/postcodes has a handy utility to look up the postcode for a Suburb or Town which you can then use to do a search.

Fantastic. I always wondered what happens if you take a mapping GPS over seas and don't have maps for it. What appears on the screen?? I have cached OS but then I only had a non mapping etrex so it didn't matter.
